9.4. 删除 DistributedComputeHCI 节点

流程

1. 复制 baremetal-deployment.yaml 文件：

   cp /home/stack/dcn2/overcloud-baremetal-deploy.yaml \
   /home/stack/dcn2/baremetal-deployment-scaledown.yaml

2. 编辑 baremetal-deployement-scaledown.yaml 文件。识别您要删除的主机，并将 provisioned 参数设置为 false ：

   instances:
   ...
     - hostname: dcn2-computehci2-1
       provisioned: false

3. 从堆栈中删除节点：

   openstack overcloud node delete --stack dcn2 --baremetal-deployment /home/stack/dcn2/baremetal_deployment_scaledown.yaml

4. 可选：如果要重复使用节点，请使用 ironic 清理磁盘。如果节点托管 Ceph OSD，则需要此项：

   openstack baremetal node manage $UUID
   openstack baremetal node clean $UUID --clean-steps '[{"interface":"deploy", "step": "erase_devices_metadata"}]'
   openstack baremetal provide $UUID

5. 重新部署中央站点。包括用于初始配置的所有模板：

   openstack overcloud deploy \
   --deployed-server \
   --stack central \
   --templates /usr/share/openstack-tripleo-heat-templates/ \
   -r ~/control-plane/central_roles.yaml \
   -n ~/network-data.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/network-environment.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/dcn-storage.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/cephadm/cephadm.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/nova-az-config.yaml \
   -e /home/stack/central/overcloud-networks-deployed.yaml \
   -e /home/stack/central/overcloud-vip-deployed.yaml \
   -e /home/stack/central/deployed_metal.yaml \
   -e /home/stack/central/deployed_ceph.yaml \
   -e /home/stack/central/dcn_ceph.yaml \
   -e /home/stack/central/glance_update.yaml
